Abstract

An extended surface area filter element construction including a central body (1) mounting a plurality of additional surfaces (2), serving to provide a greatly increased surface area as compared with a central body of the same size but not having additional surfaces that are formed by surfaces radially extending from the central body. The filter elements can be of moulded plastics and including a cylindrical tubular core from which project a plurality of radially directed fins (2) whose radial length increases stepwise from each end of the core body to a maximum length central of the length of the core body, thereby effectively to provide a generally conical double back-to-back conical appearance.
